Application filed (ictober 27, 1821. Serial No. 510,716.

The object of the invention is to proviso an ellicient construction ofstean'i boiler one furnace having; improved means for insuring; a propercirculation of the products of such conditions as to utilize mosteffectively and ecoi'iomically th heat produced by the consumption ofthe fuel, and also to p (wide a constructio which will have increasedstability 2111C strength to resist the pressures to which th same issubjected while affording ain l v means for removing accumulations ofsoo and ashes from the parts thereof so as t maintain the maximumefficiency at 2. times; and with these objects in view the inventionconsists in the construction and combination of parts of which preferretembodiment is shown in the accompanying drawings, wherein:

Figure l is a longitudinal vertical sectional view of a structureembodying the inveution.

Figure 72 a transverse sectional view on the plane indicated by the line2 2 of Figure 1 Figure 3 is a similar sectional View on the planeindicated by the line 3% of Figure 1.

Figure at is a front view of r portion of the structure showing; a otire refractory lining; thereof.

Figure is an inverted plan view of the boiler alone.

Figures 6 and T detailed sectional views on the planes indicated by thelines ($-6 and T-'T of Figure 1.

The boiler consists essentially of an outer shell or wall 10 and aninner shell or wall 11 of which the latter is arched to form acombustion chamber 1:2 spanning and er;- tcnding rearwardly from thelire box 13, the side portions of the inner wall being disposed indownwardly convergent relation with the lower portions of the outer wallor shell to form downwardly contracted longitudinal pockets 1.4;extending longitudinally of the structu e, said walls being riveted orotherwise effectively secured to longitudinal base bars 1.5 resting uponthe base plate 17 from which extend downward the angle supports 18within which and reinforced by which is arranged the masonry 20 formingthe Wall of the furnace proper which includes the above inlicated firebox 13 an ash pit 19 a bridge 1. pa t lo d proper loor 22 and boiler arethe upper and lower sets of the tubes and suitable tie rods 8 and extendng between said front and rear plates, communicating with the rear ones.res-ipectiu ;v of said upper and lower series or fire tub-es are thestack 36 provided with a suitable damper 3? a tie sn'xokc "lue whichconnnunicates with the rear end of the c inbustion chan'iber, suitableopenings 39, 4:0 and all being arranged respectively in alignment withthe upper and lower sets of fire tubes and the combustion chamber, atthe rear ends thereof and being fitted respectively with movable coversl2, and ld. The rear wall is preferably provided with a refractorylining in which the smoke flue 38 is formed, said liningextending upwardbeyond the plane of the lower series of tire tubes to a head plate 46which separates the upper end of the smoke flue from the stack.

At their front ends the upper and lower sets or series of fire tubescommunicate with a smoke box 47 fitted with a closure 48 which isconnnon to both sets of fiues gives access thereto for cleaning purposesin conjunction with the man hole covers at the rear ends of said lines.

The boiler is preferably equipped at its top with a steam gage 49, awater gage 50, suitable outlet pipes 51 and 52 respectively for steamcirculation and safety valve attachinent, and also if desired with anoutlet The combustion chamber is spanned transversel b3 front,intermediate and rear drums o6 and 5? terminally secured to the walls ofthe inner'shell 11 and in communication by means of openings 58 in saidshell with the pockets 1 so as to provide for a transverse circulationof watr between said pockets and through the combustion chamber, thefront and rear drums being disposed in pendent relation with the boilerwith their lower ends exposed and constituting downwardly deflectingbaflles for the noducts of combustion, while the intermediate drum ispre'le'ably mounted upon and forms an extension or continuation of thebi' wall to cause the products 01' combustion on leaving the fire box topass over intermediate or bridge wall drum and thence pursue a downw ;dand rearward course to pass under drun'i 5'? before entering the smokeflue 38. These drums obviously constitute effective means forcommunicating the heat of the combustion chamber to the contents of theboiler so as to etlect an economy in the use of the fuel and extract themaximum of heat units vfrom the products of combustion be-- the rearpendent bustion chamber may consist as shown of a retractory brickstructure 61 extending up iward to the bottom plate (52 ot the smoke boxa7.

la ing thus described the invention, what I claim is l. A. boilerfurnace having a boiler, a lire box, lire tubes passing through saidboiler and leading to a discharge flue, the apparatus having an outletpassage leading from the the box for products of combustion a smoke flueloading from said passage to said tubes, bal'l'les in communication withthe water space of the boiler, means mountin f the boiler and supportingone of said battles in said passageway, another of said bali'lesdepending; into said passageway between the smoke tlueiand the lastmentioned battle and providing; between the same and said means arestricted outlet for the products of combustion to facilitateprecipitation of solid matter therefrom, and a soot pocket pro vidcd insaid means located adjacent the lower end of the depending battle.

A boiler having an outer shell, an arched inner shell, said shells beingspaced art at v their side walls to constitute tets, the inner shellconstituting a coml'iustion chamber, means providing a the boxcommunication with the combustion chan'iber, supporting means for theshell enclosing the tire box having a bridge wall a d a soot pocket inthe rear thereof, a ballle member spanning the inner shell andcommunicating with said pocket and resting on said bridge wall. a battlemember depending from the inner shell spanning the latter andcommunicating with said pocket, the lastmentioned baflle extendingrelatively close to said means acent therear extremity of the pocket toprovide a restricted space to facilitate precipitation of solid matterfrom products of combustion.

In testimony whereof I al'lix my signatr EDXVARD T. MOORE.
